A "Technemo" is some who:
-Is an emo kid who also loves techno
-Loves the combination of emo music and techno music
-Dyes their hair odd colours, but only when it's paired with black
-Wear random bright/neon colours amongst their usual black clothing
Much like a "Techno Punk" and "Electro Kid".
Technemo: I like My Chemical Romance, Mindless Self Indulgence, The Used, Nine Inch Nails, Retard-O-Bot and Fall Out Boy! And look! I just dyed pink chunks into my black hair! Am I a techno punk or what?!
Techno punk: No, you're a technemo, but techno punks and technemos are so close in genre that we can be friends! Yay!
